. SHUTTLE.

Application filed March .2, 1914. SeriaI'No. senses.

To all gvhom it may concern Be it known that I, EMMANUEL LA VAL- LEE, a citizen of the United States, residing.

at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Shuttles, of which the following is a specifi cation, reference being had to they accompanying drawings, forming part thereof.

This invention has reference to improvementsin shuttles .for looms and has for one of its objects the simplification of the spindle holding device and the elimination from the shuttle" of transversely extending pins or devices which have heretofore 'beenemaployed to engage the end of the spindle and fere with any related parts of a loom in jas heretofore constructed comprise a shuttle nations of parts as shall hereinafter be more fully described and, pointed out in the claim. Figure 1, represents a plan view of the improved shuttle parts of the same being broken away. Fig. 2, represents a sectional v1ew of the shuttle taken on line 2-2 Fig. 1, the spindle holder and spindle'being showfiin full; Fig. 3, represents an enlarged detail view of the spindle-and its holder removed from the'shuttle, the spindle holder being shown in section as on line 2-2 Fig. 1 and said holderand the spindle being in position to release said-spindle.

Similar characters of reference designate corresponding parts throughout.

Shuttles of the nature herein referred to came necessary to remove the spindle 1 body having a bobbin receiving cavity-and at one end of said cavity a tubular member or socket pivotally mounted within the cavity .of the shuttle by a pin driven into a transverse hole or perforation in the shuttle body. Above and below the median line of said socket member other transverse holes were formed in the body of the shuttle and in said holes were located pins which were adapted to engage members of the spindle Specification of Letter s Patent. Patgilted Sept. 21, 1915. I i

when said spindle was inserted inthe socket member and swungdown into the cavity ofthe shuttle. Said holding pins were'merely frictlonally held in-place, and on account of vibration, often became loose enough to work outward to positions where their ends could cut or wear the reed of a-loom'on which said shuttles were used. Another cause contributing to the objection of such pins is that from time to time'it is or may be necessary to plane down or refinish the sides of the shuttle thus removing a portion ofthe wood between the point at which the outer ends of pinsare positioned and the side face ofthe shuttle so that compara *tively slight longitudinal movement of one. 'of'said pins will bring its end to'project beyond the side of the shuttle.--',WVhen itbefrom the shuttle it was necessity out at least one of said pins. '7 1 In carrying this invention into practice take a shuttle body S having the bobbin- 1 ceiving cavity C furnished with meander receiving recess D and in the side walls-bf the recess D I provide the grooves or channels (Z, (Z. The u'sual'bearing'plate E is also provided whcih is secured in place at the upper oropen .side of the shuttle by the screw F so that one of the arms of said plate extends over the recess D.

The spindle holder. comprises the base 5 having the cam shoulder 6 and side plates 7, 7 between which is the bevel edge or look ing shoulder 8. Pivotally mounted between the plates 7 7 by means of the pin 9, which preferably extends considerably beyond the outer sides of said plates; is the socket member 10 having the cam shoulder 11 and the tubular member 12 having its inner end spaced from the pin 9 sufficiently to clear the cam shoulder 6-of the base 5 so that said socket member 10 mayswing dow'nwardto into said socket member 10 and swung downward with said socket member the bevel surface 16 may ride against shoulder 6, of the spindle holder base thereby eiiecting the longitudinal movement of the spindle to engage tooth 15 of the spindle shank with the holding edge, or stop 8 of the spindle holder base whereby, when the spindle is in the position shown in Fig. 2 the disengagement of the spindle from its hold ing device is prevented. As shown herein the shank 14 of spindle 13 has the stop 1.7 which limits the movement of the spindle shank inward in" the tubular member 12 by coming in contact with the pin 9 but this stop 17 may be omitted without changing the invention and if the diameter of pin 9 be sufliciently reduced it will not be necessary to cut away any portion of shank ll to clear saidpin 9.

It is preferred to have pin 9 extend beyond the sides 7, 7 of the spindle holder in order that when said pin 9 is engaged in the grooves (Ad of the shuttle the longitudinal movement of the holder 5 is prevented but I do not intend to limit my invention in all cases to the use of such connection between the holder 5 and the shuttle.

When the parts are in position as shown in Fig. plate E bears against cam shoal Having thus described my invention 1' claim as new and desire to secure by Letters Patent.

A shuttle having a spindle receiving cavity and a recess extending in line with said cavity andv having imperforat side walls having grooves. in combination with a spindle holder removably contained within said recess and cavity and comprising a base having side walls and a locking tooth member. a pin extending through said side walls to engage with said grooves. a socket member pivotally mounted on said pin and having a tubular spindle socket open at its rear end. a spindle slidable in said socket and having a tooth to engage with the locking tooth member at one edge and a cam adapted to ride against said tooth member to effect such engagement between the tooth ofsaid spindle and the tooth member.
